NR-10 – Safety in Electrical Installations and Services

NR-10 regulates the safety and health of workers who interact with electricity in Brazil.

NR-10 was first published in 1978, based on the French standards, and revised four times, in 1983, 2004, 2016 and 2019, to reflect the changes in the sector and the legislation.

It applies to any installations and services with electricity, in its various uses and applications, and any work performed near them, regardless of the voltage level or the type of activity.

It establishes the basic guidelines for the implementation of control measures and preventive systems, such as risk assessment, safety procedures, training, qualification, authorization, personal protective equipment, emergency plans, etc. It also creates the National Permanent Commission on Safety in Electric Energy (CPNSEE), a permanent commission to monitor and propose improvements to the NR-10.
